Bug 288927

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I was shutting down the computer. The same crash as with my desktop, but this time with my laptop. As I said this happens with both computers.

The crash can be reproduced every time.

-- Backtrace:
Application: Shell de escritorio Plasma (plasma-desktop), signal: Segmentation fault
